FRED A. WI-IITMORE, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO CROMPTON& KNOWLES LOOM WORKS, A CORPORATION OF MASSACHU- SETTS.

BALL-WINDER.

Specification of Letters Patent.

Patented Maren 12, 1907.

To all whom it may concern:

Be it known that I, FRED A. WHITMORE, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and and State'of Pennsylvania, have invented certain new and useful Improvements inBall-Winders, of which the following is a specification.

My invention relates to ball-winders, so termed, which are used forwinding yarn or sliver into a ball, ready for the comb; and my inventionparticularly relates to improvements in the stopping and lockingmechanism for the rotary and longitudinall -movable spindle, on whichthe yarn or liver is wound, in the class of machines referred to.

The object of my invention is to provide an improved construction of thestopping and locking mechanism for the spindle on which the yarn orsliver is wound.

My invention consists in certain novel features of construction of myimprovements, as will be hereinafter fully described.

I have only shown in the drawing a detached portion of a ball-winderembodying my improvements, sufficient to enable those skilled in the artto understand the confstruction and operation of the same.

Referring to the drawing, Figure 1 is a front view of a ball-winder headembodying my improvements, with the spindle and disk and hand-wheelpartially broken away.

Fig. 2 corresponds to Fig. 1, but shows some of the parts in theopposite position. The complete hand-wheel is shown in this figure. Fig.3 is a section on line 3 3, Fig. 1, looking in the direction of arrow a,same figure. The upper part of the hand-wheel (not shown in Fig. 1) isshown in this figure.

In the accompanying drawing, 1 is the ball-winder stand adapted to bemounted and fastened on a table or suitable support (not shown) byscrews 1 and having thereon the spindle-bearing or head 2.

3 is a disk or plate loosely mounted on the head 2.

4 is the spindle having the tapering and square-shaped end 4, on whichthe yarn or sliver (not shown) is wound. The spindle 4 has a rotary anda longitudinally-reciprocating motion within the head 2 and has looselymounted thereon and connected therewith a sleeve 5, having a rack orteeth 5 thereon, which are adapted to mesh with the teeth on a pinion 6,which is fast on a rotary shaft 7, mounted in suitable bearings on theunder side of the head 2. The shaft 7 has a rotary movement communicatedthereto in one direction or the other by a hand-wheel 8, having in thisinstance two handles 8.

All of the above-mentioned parts exceptthe construction of thehand-wheel 8 may be of the usual and well-known construction inball-winders of the class referred to.

I will now describe my improvements. On the shaft 7 is loosely mountedthe hub 9 of a segment 9, which as it is moved around on the shaft 7will come in contact with a stationary stud or stop 10, secured in thelower side of the head 2. On the shaft 7 is splined the hub 11 of an arm11. The arm 11 at its outer end carries a stud 12, which is looselymounted to have a rotary movement. On one end of said stud 12 is fast anarm or lever 13, which extends between two lugs or projections 8" on theinner side of one of the spokes of the hand-wheel 8. On the other end ofthe stud 12 is fast a catch or pawl 14, which is adapted to engage astud 15, in this instance adjustably secured in an elongated slot 2 inan extension 2 on the head 2. A spring 16, in this instance ahelically-coiled spring, is attached at one end to the arm 11, and atits other end is connected with the pawl or catch 14 and acts to raisesaid pawl or catch 14 to engage the stud 15 when said pawl or catch isnot .moved out of engaging position by the movement of the arm or lever13. The segment 9 has a lug or projection 9 thereon, which extends inthe path of and is adapted to be engaged by the arm 11 as said arm isrotated with the shaft 7 i The hand-wheel 8 has its hub loosely mountedon an extension of the hub 11 of the arm 11. (See Fig. 3.)

The operation of my improvements will be readily understood by thoseskilled in the art. Supposing the parts of the machine to be in theposition shown in Fig, 1, with a full ball of yarn or sliver (not shown)on the end 4 of the spindle 4 ready to be. doffed or removed, thehand-wheel 8 through one or both of the handles 8 is turned to the leftin the direction indicated by arrow 6, Fig. 1, and the engagement of thelug 8" at the right, Fig. 1, on a spoke of the hand-wheel with the armor lever 13 will move said arm or lever to the left, Fig. 1, and throughthe rocking of from the stud 15, against the action of the spring 16 andrelease the arm 11, fast on the of pile-warp or remove it from thespindle will cause the unlocking of the hand-wheel and shaft 7, andallow the rotation of said shaft l other parts and allow thelongitudinal moveand the pinion 6, fast thereon, and cause the ment ofthe spindle to a predetermined dismovement, through the rack-teeth 5, ofthe sleeve 5 and the spindle 4, attached thereto, to move the spindlewithin the head 2, as shown in Fig. 2. There is in this instance nearlyone revolution of the hand-wheel 8 and the arm 11 and shaft 7 before thearm 11 engages the lug 9 on the segment 9, loose on the shaft 7, andnearly one-half revolution of the hand-wheel 8 before the segment 9moves from the position shown in Fig. 1 to the position shown in Fig. 2and into en agement with the stud or stop 10, which stops any furthermovement of the segment 9 and through scribed a hand-wheel; but it willbe understood that, instead of awheel, a hand-lever or crank-arm orother suitable device may be the engagement of the arm 11 with the lugor used.

projection 9 stops any further movement of Having thus described myinvention, what the arm 1 1, the hand-wheel 8, and the shaft I claim asnew, and desire to secure by Letters 7. The movement of the hand-wheel 8to Patent, is

withdraw the spindle 4 to doff or remove the l 1. In a ball-winder foryarn, &c., the comball of yarn or sliver is in this instance about Ibination with a hand-wheel for moving lonone and one-half turns. To movethe spindle 4 in the opposite direction and out of the head Zpreparatoryto the winding of another ball thereon,- the hand-wheel 8 is moved inthe opposite direction or in the direction indicated by arrow 0, Fig. 2.Nearly one revolution of the hand-wheel 8 will be made, and then the arm1 1 will engage the projection 9 on the segment9 in the oppositedirection from that shown in Fig. 2 and move said segment around untilit engages the stop or stud 10, as shown in Fig. 1. The engagement ofthe segment 9 with the stud 10, as shown in Fig. 1, stops the rotarymovement of the arm 11, hand-wheel 8, and shaft 7, and at the same timethe spring 16 acts toraise the pawl or catch 14 to engage the stud 15and lock the hand-wheel 8, arm 11, and shaft 7 in position.

The advantages of my improvements will be readily appreciated by thoseskilled in the art. The hand-Wheel and other parts are thusautomatically locked in position when the spindle is in its inwardposition, as shown in Fig. 1, and the ball of yarn or sliver isbegitudinally, through intermediate mechanism, the spindle on which theyarn is wound, of a positive stop for the hand-wheel on the outward andinward movement of the spindle, and locking mechanism for automaticallylocking and holding the spindle in its inward position.

2; In a ball-Winder for yarn, &c., the combination with the spindle onwhich the yarn is wound, a rack connected with said spindle, a pinionfor moving said rack, a rotary shaft carrying said pinion, and ahand-wheel for rotating said shaft, of connections intermediate saidhand-wheel and shaft, and means for positively stopping the rotation ofsaid handwheel and said rotary shaft in each direction, at the end ofeach longitudinal movement of said spindle, and means, automaticallyoperated, for holding and locking the rotary shaft when the spindle isin its inward position.
